DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a suede-like surface-imparting material, a decorative sheet, a transfer foil, and an embossed material used for imparting a soft and outstanding matte appearance such as suede. It relates to a shape film.

[Conventional technology]

In various fields such as furniture, building materials, and weak electric appliances, various means have been adopted to make the surface matte.

For example, there is a method of directly applying a suede paint (matting ink) obtained by adding a bead pigment such as an acrylic bead or a nylon bead to a vehicle to a solvent-soluble resin material on a target object surface. There is a problem that coating unevenness is likely to occur on the surface, a uniform and beautiful matte surface cannot be obtained, and the cost is high. The above-mentioned bead pigment refers to a fine powder surface of a usual pigment such as Fe ₂ O ₃ , TiO ₂ , CaCO ₃ , quinacridone, polyurethane, acrylic, epoxy, polyester, nylon, fluororesin, vinyl chloride vinyl acetate copolymer The vehicle is coated with an elastic resin such as, for example, and the vehicle is one used for ordinary ink, for example, a urethane resin.

〔Example〕

 Hereinafter, embodiments of the present invention will be described with reference to the drawings.

The suede-like surface-imparting material 1 of the present invention is provided with at least a resin layer 4 which is a suede-like surface 3 having a concave portion 2 having an inner expanding shape as shown in FIG. The suede-like surface 3 is made of a substrate 14 as shown in FIG.
As shown in FIG. 3, the surface shape of the fine uneven coating layer 5 is formed on the surface of the resin layer 4 by using the shaping film 6 provided with the fine uneven coating layer 5.

The above-mentioned fine unevenness coating layer 5 has a surface where the center of gravity X of the fine particles protrudes from the average level surface H of the binder component coating film using a releasable binder resin 8 to which fine particles 7 having a spherical shape or a sphere-like shape are added. It is a coating layer which is formed so as to have a state and has a surface gloss value of 0.5 to 2.0% and a surface roughness of 1 to 30 μm. Center of gravity X of fine particles 7
Is in the state as described above because, after all, the protrusion of the fine particles 7 needs to be in the form of spreading outward. The shape of the fine particles that can adopt such a protruding form is generally a spherical shape, and in addition, an ellipse, an eggplant shape, and a cardioid similar to a spherical shape having a smooth surface are represented by a symmetric axis. And the shape of a rotating body or the like that has been rotated. The average standard surface of the binder component coating film refers to a position on the coating film surface where no fine particles 7 are present. The surface gloss value is measured by a specular gloss measurement method according to JIS Z8741, and the surface roughness is represented by the distance from the average standard surface to the top of the fine particles 7.

In the present invention, since the suede-like surface 3 is obtained by shaping with the shaping film 6 having the above configuration, the concave portion 2 is formed.
Has an expanded shape inside the opening compared to the opening, that is, an inwardly expanding shape, and the surface gloss value (75 ° incidence) on the suede-like surface 3 is 0.1 to 1.0%.
As a result, an excellent super matte appearance appears from the surface 3.

As the fine particles 7, for example, silica, alumina, calcium carbonate, precipitated barium sulfate, clay, silas barium, benzoguanamine, talc and the like can be used. The particle size of the fine particles is about 1.3 to 40 μm, preferably about 2 to 10 μm. The amount of the fine particles added to the binder resin is appropriately adjusted depending on the surface gloss value of the coating layer 5 and the like.

The release binder resin is not particularly limited and may be a base material.
What is necessary is that it has good adhesion to 14 and good releasability to the other side (resin layer) when the shaping film 6 is peeled off. As the base material 14 of the shaping film 6, polyester, polyethylene, polypropylene, polyamide, acrylic, polycarbonate, polyacrylate, polyvinyl chloride, polyethylene terephthalate, polystyrene,
A film made of polyvinyl fluoride, polytetrachloroethylene, Teflon, polyvinylidene fluoride, polyvinyl alcohol, polyetheretherketone, polyimide, polybutylene terephthalate, cellophane, etc. can be used alone, or these films can be appropriately bonded together, or the resin can be used. Directly applied to form a laminated film,
Or, a film composited with an aluminum foil or the like can be mentioned, and among them, a polyester film is most preferable.

The resin material of the resin layer 4 may be any material other than the thermosetting resin, such as a thermoplastic resin or an electron beam curable resin. When the resin layer 4 is made of a thermosetting resin, there is a problem that the temperature of the thermosetting is high and the printed sheet is likely to be distorted due to the high heat during the curing. The resin layer 4 may be optionally colored to enhance the matting effect.

The suede-like decorative sheet 9 of the present invention comprises at least only the resin layer 4 as shown in FIG. Further, as shown in FIG. 4, the decorative sheet 9 is configured such that the resin layer 4 is composed of an electron beam-curable resin layer 4a, and a polyvinyl chloride film 10 is provided on the lower surface of the resin layer 4a. In the decorative sheet 9, a matting agent such as silica or alumina is used as the fine particles 7,
It is preferable to use a copolymer resin or a mixed resin composed of a thermosetting type allyl / urethane as a binder resin. With such a configuration, the holding power of the matting agent, the matting state, the low glossiness, the surface scratch resistance, There is an advantage that a decorative sheet excellent in abrasion resistance and the like can be easily obtained.

In the case of the decorative sheet 9 having the structure shown in FIG. 4, it is preferable to use polyester, acrylate, urethane acrylate, 2-hydroxyethyl acrylate, neopentyl glycol diacrylate, or the like as the electron beam curable resin. The production of the decorative sheet 9 is performed, for example, by applying an electron beam curable resin to a polyvinyl chloride film 10 and then superimposing the shaping film 6, and then irradiating an electron beam to cure the curable resin. At the same time, it is brought into close contact with the film 10, and finally the shaping film 6
By peeling off, a decorative sheet in which the suede-like surface 3 is formed on the surface of the cured resin layer can be obtained.

As shown in FIG. 5, the suede-like transfer foil 11 of the present invention has a suede-like surface 3 having at least the above-described inflated concave portion 2 on a shaping film 6 as shown in FIG. It is configured by providing a shaping resin layer 4b for shaping. If necessary, a decorative layer may be formed on the resin layer 4b.
12, an adhesive layer 13 and the like can be provided. According to this transfer foil, the resin layer 4b having the suede-like surface 3 formed on the surface thereof is transferred by peeling off the shaping film 6 after the resin layer 4b is overlapped so as to be in contact with the transferred body. Can be transcribed on the body side.

As the material of the shaping resin layer 4b, the same material as the material of the resin layer 4 can be used. As the decorative layer 12, a coloring layer or a picture layer can be formed by using a general printing ink, and the matting effect of the resin layer 4b can be further enhanced by giving an appropriate coloring to the coloring layer. The adhesive layer 13 can be formed using an adhesive appropriately selected according to the material of the transfer target, and is generally an acrylic resin, a vinyl chloride-vinyl acetate copolymer,
An adhesive such as a rubber-based resin or a thermoplastic urethane resin alone or as a mixture can be used. Although not particularly shown, a primer layer may be provided using the same printing ink or the like used in the decorative layer 12 next to the resin layer 4b in the transfer foil 11,
By providing this primer layer, post-processing such as formation of a decorative layer or an adhesive layer can be facilitated during the production of the transfer foil, and the resin layer 4b can be transferred with good smoothness after the transfer. .
